Health awareness rotorcraft

connected rotocraft solutions

GE’s Health and Usage Monitoring System uses data insights to improve mission readiness, safety, and lower operational costs.

GE’s Health and Usage Monitoring System (HUMS) unlocks operational data insights to detect rotorcraft safety events and reduce ongoing maintenance lifecycle costs.

  • Save technicians maintenance hours such as removal time, test runs, and post service actions.
  • Reduces the need for temporary equipment for the most common repetitive activities.
What is GE’s Health and Usage Monitoring System?

GE’s HUMS improves mission readiness, safety, and sustainability with data insights

Connect to safety

HUMS is an end-to-end health awareness system monitoring rotorcraft systems data like:

  • airframe
  • engine and drivetrain vibration
  • exceedances
  • chip detections
  • balance, HUMS uses GE proprietary algorithms that can be configured by OEM’soperators to enable preventive repairs instead of major maintenance actions.

Understand maintenance and availability

HUMS enables accurate, configurable usage counting for effective airframe and component life management.

  • Improves mission readiness with actionable data insights across your member systems
  • Conducts root cause analysis for improved fault isolation
  • Facilitates planned maintenance and
  • Reduces trouble shooting.

Manage costs

Saves up to 10x the acquisition costs by automatically decoding, storing, analyzing and distributing data to key stakeholders to enable efficient maintenance operations. Provides visibility to and analysis of key performance indicators across rotorcraft and fleet-wide operations.

Enables reduction in cost of rotor track and balance activities


Incident


Failure to manage vibrations caused by out of balance or off-track rotors will eventually lead to long-term damage to airframes, avionics, and drivetrain components. Requires frequent need to apply track and balance adjustments to ensure vibrations remain within acceptable tolerances.


Response


GE’s HUMS helps reduce unplanned maintenance from excess vibration,capturing data on every flight so you can proactively know when you need to make rotor adjustments.


Value


Immediate ROI on rotor track and balance by reducing the need for additional test flights.

Reducing No Fault Found (NFF) for Rotorcraft


Incident

Incorrectly identifying failed components and systems leads to increased maintenance costs and reduced mission availability of the rotorcraft. No Fault Found (NFF) leads to increased repair time and maintenance efforts.


Response


GE’s Health Awareness System (HAS) software product that combines the best of predictive analytics and configurability from commercial fixed wing solutions with rotorcraft health and operational flight data. GE HAS manages the health of the entire rotorcraft integrated within existing or new sub systems including Health and Usage Monitoring System (HUMS), network switches and/or other line replaceable units (LRUs).


Value


Root cause analysis of reported failures can eliminate excessive inventory of spare parts and systems. Reduces unnecessary removal, inspection and test of components driving down maintenance costs and time. Data driven analytics leads to “right fix at the right time” increasing rotorcraft availability.

Accurately monitor Exceedance Based Events to perform required maintenance and ensure air worthiness limits.


Incident

Rotorcraft crew reports significant parament exceedance overload. This overload can cause damage to the drivetrain and could require the rotorcraft be pulled out of service and inspected.


Response

GE HUMS automatically and continuously records operational flight exceedance parameters set to OEM derived limits and determines the magnitude of the overload exceedance immediately. Data from before, during and after the event is analyzed to visualize trends, manage severity levels and time of duration of the exceedance.


Value


Manage costs and implement “right fix at the right time” by using mission critical recorded flight data to determine the correct maintenance actions. Eliminate ambiguous reports and add additional layer of protection to the rotorcraft and fleet by accurately recording and reporting exceedances from the member systems.

Early detection of critical component failure improves safety and prevents further damage and costs.


Incident

Incorrectly torqued bolts or faulty manufactured gears/bearing may cause excessive vibration, loss of power requiring the replacement of expensive drivetrain parts.


Response

GE HUMS can provide early warning of these types of problems before long lasting damage may occur to your mission critical systems. The maintainers are provided easy to understand condition indicators that make it simple to take corrective action. Analyses have proven that the GE HUMS system can correctly isolates faults, detects events and prevents subsequent damage. The technology can pinpoint the exact bearing component type raceway or roller that is beginning to fail.


Value


Early identification of problems with mission critical systems such as drive trains provides operators with timely options. Eliminating unplanned maintenance reduces operational costs and can help minimize safety of flight situations from component failure.

Health Usage Monitoring System lifecycle

1

Pre-Flight

Configure the HUMS system and set up the analysis based on rotorcraft type and mission operational parameters. Analysis and configuration include (but are not limited to) rotor track & balance, gear box vibration, and rotorcraft exceedances.

2

In-Flight

GE provides automatic, real-time monitoring, display, and recording of rotorcraft operational conditions. This occurs at the component level, which includes rotor track, drive train vibration, temperature, pressure, speeds, and usage counts. GE conducts a complete health assessment while the rotorcraft is in flight.

3

Post-Flight

GE transfers data and analysis results to a ground station for review of alerts and maintenance events by the support crew.

4

Ground

GE provides data storage, forwarding, live-data viewing, and analytics for long-term health trending and analysis.
